The population growth rate refers to the rate at which a population increases or decreases over time. It is determined by the difference between birth rates and death rates, as well as immigration and emigration.
Carrying capacity refers to the maximum number of individuals that an environment can sustainably support.
Zero Population Growth: Zero population growth occurs when birth rates equal death rates, resulting in no net increase or decrease in the size of a population.
